Failed! ## Trying with polynomial interpretations... The constraints are satisfied by the polynomials: {+(_0,_1):[_0 * _1], f(_0):[2 * _0], +^#(_0,_1):[_0 + _0 * _1]} for all instantiations of the variables with values greater than or equal to mu = 2. This DP problem is finite. ** END proof description ** Proof stopped at iteration 0 Number of unfolded rules generated by this proof = 0 Number of unfolded rules generated by all the parallel proofs = 28
